The most consensual story about the origin and invention of the Francesinha relates to a returned emigrant from France and Belgium, Daniel da Silva. In 1953 when returning to Porto, Mr. Da Silva decided to completely change the French traditional “croque-monsieur”, adding layers of different types of meat and cheese as well as a secret and spicy sauce on top of the sandwich.

The baptism of Francesinha (translates as Little French Girl) is credited to the fact that Mr. Da Silva commonly stated among friends that “The spiciest women I know are the French girls!”. The statement was perfect for the hot and spicy secret sauce he invented for the sandwich and the “Francesinha” was born.
